The ecc.size for mxs NAND driver is set to 1 in Linux kernel and to 512 in U-Boot, which causes "ubi part" command malfunction due to wrong subpage size.

ecc.size = 1 doesn't make sense -- this is the block size over which ecc is calculated.
Where is this Linux driver? I don't see mxs_nand.c in Linux.
What specifically is happening in "ubi part" with ecc.size = 512?
